Cooking a bone-in ham is a culinary tradition that brings warmth and a sense of celebration to any table. Whether you are preparing a centerpiece for a holiday feast or looking to master a weekend family dinner, understanding the nuances of selecting, preparing, and glazing a bone-in ham is essential. Unlike its boneless counterpart, a bone-in ham offers superior flavor and moisture, thanks to the bone conducting heat and infusing the meat with depth as it cooks.
Choosing the Right Bone In Ham
Before you even turn on your oven, the success of your meal begins at the butcher counter. Most hams sold in grocery stores are “city hams,” which means they have been wet-cured and are usually pre-cooked or smoked. When you see a label that says “ready to eat” or “heat and serve,” you are essentially reheating the meat rather than cooking it from a raw state.
When selecting your ham, look for one that has not been overly processed. A “ham with natural juices” is generally higher quality than a “ham with water added,” as the latter can have a spongy texture and diluted flavor. The size is also a critical factor. A good rule of thumb is to allow for about 3/4 pound to 1 pound of meat per person. This accounts for the weight of the bone and ensures you have enough for those highly coveted leftovers.
Preparation and Tempering
One of the most common mistakes when cooking a bone-in ham is moving it directly from the cold refrigerator to a hot oven. For an even cook, it is vital to let the ham sit at room temperature for about 1 to 2 hours before roasting. This process, known as tempering, ensures that the center of the ham reaches the desired temperature without the exterior becoming dry and overcooked.
While the ham is tempering, take a moment to inspect the skin. If your ham has a thick layer of fat and skin, you may want to score it. Using a sharp knife, create a diamond pattern by cutting crosswise lines about 1 inch apart and 1/4 inch deep. Scoring does more than just make the ham look professional; it allows your glaze to penetrate deeper into the meat and helps the fat render out beautifully.
The Roasting Process
To begin, preheat your oven to 325 degrees Fahrenheit. Low and slow is the secret to a juicy ham. High temperatures will cause the exterior to toughen before the heat can penetrate the bone.
Place the ham in a heavy roasting pan. If the ham is a half-cut (which is most common), place it flat-side down. This protects the most tender part of the meat from direct heat. To create a moist environment, add about a half-inch of liquid to the bottom of the pan. While water works perfectly fine, you can add layers of flavor by using apple cider, pineapple juice, or even a splash of dry white wine.
Cover the roasting pan tightly with heavy-duty aluminum foil. This step is non-negotiable. The foil traps the steam generated by the liquid, essentially braising the ham and preventing the moisture from evaporating. Without a tight seal, you risk ending up with a dry, leathery roast.
Calculating Cook Time
Since most bone-in hams are pre-cooked, you are aiming for an internal temperature of 140 degrees Fahrenheit. On average, you should plan for 15 to 20 minutes of cook time per pound. For a 10-pound ham, this means a total time of roughly 2.5 to 3 hours.
However, do not rely solely on the clock. Every oven is different, and the thickness of the bone can affect how heat travels. Use a meat thermometer inserted into the thickest part of the meat, making sure it does not touch the bone itself, as the bone will give an inaccurately high reading.
The Art of the Glaze
The glaze is where you can truly express your culinary personality. While the ham is in the oven, you can prepare a mixture that balances sweetness, acidity, and spice. A classic glaze often involves brown sugar or honey as the base, mixed with Dijon mustard for tang and warm spices like cloves, cinnamon, or ginger.
Timing the glaze is critical. Because most glazes contain high amounts of sugar, they will burn if applied too early. Wait until the ham has reached an internal temperature of about 120 degrees Fahrenheit. Remove the ham from the oven, increase the oven temperature to 400 degrees Fahrenheit, and carefully peel back the foil.
Generously brush the glaze over the entire surface of the ham, ensuring it gets into the diamond scores you created earlier. Return the ham to the oven, uncovered. Continue to roast for another 15 to 20 minutes, basting with more glaze every 5 to 7 minutes until the exterior is caramelized, bubbly, and a deep mahogany brown.
Resting and Carving
Once the ham reaches an internal temperature of 140 degrees Fahrenheit, remove it from the oven. It is tempting to slice into it immediately, but patience is rewarded. Tent the ham loosely with foil and let it rest for at least 15 to 20 minutes. Resting allows the juices to redistribute through the fibers of the meat, ensuring every slice is moist.
Carving a bone-in ham may seem intimidating, but it follows a logical path. Position the ham so the bone is visible. Cut a few slices from the thinner side of the ham to create a flat base, then turn the ham onto that flat side so it stays stable. Slice vertically down to the bone across the top, then make a horizontal cut along the bone to release the slices.
Flavor Variations and Ideas
While the classic honey-mustard glaze is a staple, don’t be afraid to experiment. For a Southern twist, try a glaze made of bourbon, maple syrup, and a pinch of cayenne pepper. If you prefer something bright and tropical, a combination of pineapple juice, brown sugar, and maraschino cherry juice creates a nostalgic, vibrant finish. For a more savory profile, consider a glaze of balsamic vinegar, fig preserves, and fresh rosemary.
Using the Leftovers
One of the greatest benefits of cooking a bone-in ham is the leftovers. The meat can be used for sandwiches, breakfast hash, or diced into a creamy pasta carbonara. Perhaps most importantly, never throw away the ham bone. The bone is a goldmine of flavor and gelatin. It can be simmered in a pot of water with aromatics to create a rich stock for split pea soup, navy bean soup, or slow-cooked collard greens.
Frequently Asked Questions
-
Do I need to wash the ham before cooking it?
No, you should not wash the ham. Modern food safety guidelines advise against washing raw or pre-cooked meat as it can spread bacteria around your kitchen surfaces. Any surface bacteria on the ham will be destroyed by the heat of the oven. Simply pat the ham dry with paper towels if it is excessively wet from the packaging.
-
What if my ham is labeled “Cook Before Eating”?
If your ham is not pre-cooked (which is rare in standard grocery stores but common with fresh hams or some country hams), you must cook it to a higher internal temperature. A fresh, raw ham must reach an internal temperature of 145 degrees Fahrenheit to be safe for consumption. Always check the packaging carefully to determine if your ham is “ready-to-eat” or “requires cooking.”
-
How do I prevent the ham from drying out?
The most effective ways to prevent drying are keeping the oven temperature low at 325 degrees Fahrenheit, adding liquid to the bottom of the pan, and sealing the pan tightly with aluminum foil for the majority of the cooking time. Only uncover the ham during the final 20 minutes when you are applying the glaze and browning the exterior.
-
Can I cook a bone-in ham in a slow cooker?
Yes, a bone-in ham can be cooked in a slow cooker if it fits. This is a great way to save oven space during holidays. Place the ham in the slow cooker with your liquid of choice and cook on low for 4 to 6 hours. However, you will miss out on the crispy, caramelized exterior that an oven provides. You can solve this by transferring the ham to a hot oven for 10 minutes at the very end to set the glaze.
-
How long can I keep the leftover ham in the fridge?
Cooked bone-in ham will stay fresh in the refrigerator for 3 to 5 days when stored in an airtight container or wrapped tightly in foil. If you cannot finish it within that timeframe, ham freezes exceptionally well. You can freeze sliced or diced ham for up to 2 months. The ham bone can also be frozen for several months until you are ready to make a soup or stock.
